Ok so what I really need to do is find another 1971 bottom half of the crankcase.Did you say you had one?I'm just not keen on not having anything there as I would think the oil would leak from the outside of the oil seal.

I should have one according to my records, so i will get out there tomorrow arvo and have a dig around.

Cool thanks man.

Are you sure its a bush and not just a melted lump that used to be string or rope???


Ive had a few apart and i havent found a bush like that.

Actually, Jeffery, Now that bob has mentioned that, And i have had a closer look, The one i have found here for you (first four digits 5271) is exactly the same, just without the large sleeve over the end.

Everything else is a match, and there is no plastic bush on mine, the washer with the 2 holes just fits snugly to the shaft when its pressed down into place.

I can assure you it is a bush no melted plastic or string or rope.The washer I have doesn't lock in at all.I will get it out of the create it's in this afternoon and have another look more closely.I let you know what my findings are.

Well, as soon as I can, I will give you the one i have here for you too, and you can see where they are similar, and where they are different.

It is possible, that if you want to keep yours, you could just use the washer from mine (needs no bush) and keep the rest of mine as spare, then you will be able to keep as much original engine as possible!

Just found out a bit more about this.

The sleeve was there on some models as a mesure to prevent the alloy splitting or deforming when the bearing was inserted (from the bottom up on these ones)

The washer seems to come in both bush or no-bush variants, and is a simple dust/grass/debris cover for the bearing, to prevent grass, plastic or rope making it into theactual bearing.

It seems the non-bush, and bush type dust washers are interchangeable.

That's all good news.I see you did add it.Should have looked here first.

Ty I thinking I may have found a different's between Mark I,II and III base's.On the Mark I & 2 where the height adjuster spring attaches to the base.There is just the one pin coming off the base.On the Mark III there is that one pin as well as a guide pin as well.Here let me show you.




As you can see here they have only the one upright pin for the spring.The very dirty one is my original Mark I.The one with the crack on the side.The other one was my first VC the Mark II.




Now these ones have the two pins.Now the one that is still semi green you will remember that is the Mark III that I picked up last weekend.The grey is the one that I got from you.So can you remember if it was a Mark III.I'm thinking from my investigation it was.

Ok, The two bases that you have already started are the MKI & MKII Bases.

The base that does not have the Guide post is the MKI Base i gave you, The one with the post, and the I cast near the engine mounts is the MKII you first started with (right back at the begining!)

The new base, from the coast is a MKIIIB base, it was cast in the same mold as the first series of VC-160 Auto Drive, But does not have the cut out for the belt to pass through, however it does have the spacing for the belt to run around the pulley, and other casting marks for the Auto.

There is another type of base, the normal MKIII, or MKIIIA, it has the same engine mount area (no belt space) as the first two, but is a MKIII base. I have one here for you.

The MKIIIA also had a slightly different cowl to the MKIIIB, the MKIIIB has a smoother lip around the hole for the starter, While the MKIIIA cowl, is the same as a standard MKII Cowl, wich still shows casting indentations for the starter cover used on the MKI

I'm not sure I completely followed you there.I think I got confused.The base with the guide post is the one I got of you.It also had the letter I between the engine mount bolt holes at the back of the base.I'm sure I posted pictures of them in the other VC topic.The one that is now closed.Also when I looked in my photos of the Mark I & II when I first got them I can clearly see no guide post.That's what I trying to work out.From what I can see here that one does appear to be a Mark III base.As the other one I have here is almost the same.There are also some little different's under the base.It looks to be more about strengthening the exhaust hole.My problem is I can't really use a Mark III base to do a Mark I or II.It wouldn't be right.So that's what I'm trying to find out if it is a Mark III.If it is I may have to cut the post off so at least it would be visually right.

The one with the I and the post is a MKII, it is a later MKII, cast in the later half of the MKII run.

The one with one post is the MKI i gave you to replace the cracked MKI one you already had.

The MKIII you have is actually an MKIIIB, as it has the belt runner for the Auto Drive.

The later MKII's and all MKIII's had the guide post.

So would that be 1972 or 1973?

Would Witch be 72 or 73?

If you look at the seized engine from the First VC-160 you got, the serial will tell you the year of the base with the I

If you look at your MKIII engine, from the coast, that will tell you the age of the late VC-160 and it's base.

And I remember your MKI engine is 1970, and i can confirm the engine i took off that base (the one with only one post) was a 1970 engine.

No I think your getting mixed up.The one with the I and the guide post is the one I got of you.Have a look back in the post Rant about VC and there I commented about the different cast marks and the I.That's why I'm trying to work out what it was, with year and exactly what it was.Don't you think if it was I had got that I would be asking questions like that?As I said I have pictures here of when I got them and none except the Mark III have the guide post.

Jeffery, I have looked back to the original post, HERE, and as you can see, you are the one who originally said that the one with the I was your original MKII.

The one with the I is a MKII, not a MKIII, and would be most likely a 1971 base, I believe your seized original motor confirms this.

the one With one post is a MKI, not a MKII, and is a 1970 base, I have it's engine here.

The MKIII is the one with the belt guides.

I have also now checked every one i can find.

Both my MKI's have no guide post
My MKII's have a guide post
One of my MKIII's has a guide post and belt runners
Two of my MKIII's have guide posts and no belt runners

Well that's all I wanted to know now.I don't have to cut it off.Which is good as I so far have spent many hours getting it ready.I really didn't want to have to cut it off.It's almost ready for paint.Not that I can at the moment [Censored] whether.

Make sure to write it down this time so you dont mix them up when you are putting them back together.

The one with one post is the MKI i gave you, it goes with the engine that has a serial starting with 52700, which i beleive you have already restored.

The one with the 2 posts is your original MKII, and needs an engine with 52710 on it, as the original (Seized) engine most likely would have had, You should have most of the parts for this engine now, between what you saved of the original engine, and what i have given you, though i do have a dust-seal washer, and a lower crank case for this.

the one with the belt runners is a later MKIII, if you need to replace the cowl for this one, make sure the lip on the cowl, around the starter, is smooth, and continuous.

I have an early MKIII here for you, it is very similar to your MKII base, and must be matched with a cowl of the same type, the lip around the starter hole on this cowl, will have 3 indents, that mark where screws were drilled in for the MKI (as it was cast from the same mold)
